6-7 Power Supply
The 6028R-E1CR12T has a 920 watt redundant, hot-plug power supply consisting
of two power modules. Each power supply module has an auto-switching capability,
which enables it to automatically sense and operate at a 100V - 240V input voltage.
Power Supply Failure
An amber light will be illuminated on the power supply when the power is off. An
illuminated green light indicates that the power supply is operating. If either of the
two power supply modules fail, the other module will take the full load and allow the
system to continue operation without interruption. The Power Fail LED on the front
control panel will illuminate and remain on until the failed unit has been replaced.
Replacement units can be ordered directly from Supermicro. The power supply
units have a hot-swap capability, meaning you can replace the failed unit without
powering down the system.
Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply unit. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the same model (see part number in the Ap-
pendix), which can be ordered directly from Supermicro.
Removing the Power Supply (Figure 6-9)
1. First unplug the AC power cord from the failed power supply module.
2. Depress the locking tab on the power supply module.
3. Use the handle to pull it straight out with the rounded handle.
Installing a New Power Supply
1. Replace the failed hot-swap unit with another identical power supply unit.
2. Push the new power supply unit into the power bay until you hear a click.
3. Secure the locking tab on the unit.
4. Finish by plugging the AC power cord back into the unit.
